Which super popular game were you utterly disappointed by?

@dpunked Ooof, most disappointed I've been with a game has to be Cosmic Encounter; it's primarily rooted in two things.

1. I had a terrible first play. I won (no ties even), but it felt vapid and arbitrary.
2. The inability to select a target (and thus negotiate accordingly) sort of removed where I was hoping the game would be. Instead it was "oh, I'm targeting Jerry cause the game told me to"

Someone else in the group brought it, so it's not like I was out any skin. The game I did purchase, played a lot of to confirm some suspicions, and then traded away was Terra Mystica:

1. It has a declining critical nature of decisions as the game progresses (the three most important decisions you'll make in the game are during setup).
2. I found the faction dictated my strategy at an almost claustrophobic level (in particular, digging costs). This came across as a game about "here is what you need to do, can you do it better." Ora & Labora gives you a ton of options each turn and some of those are legitimate but it depends on your goal. TM says "here is your goal and strategy, can you actually do it" which I was less interested in.

I played maybe 7 or 8 games in person and double digits online but haven't played in years...
